The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

• Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
• Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

If using forms-based authentication, SSL is required. For redirection to occur, the target OWA virtual directory must have an ExternalURL value.
• Manual: Users receive a notification that they are accessing the wrong URL and that they must click a link to access the preferred Outlook Web App URL for their mailbox. This notification occurs only when the Client Access server determines that it must redirect an Outlook Web App request to the Client Access server infrastructure in another Active Directory site. For redirection to occur, the target OWA virtual directory must have an ExternalURL value.

The default value is Manual.

Parameter sets

-ExtendedProtectionFlags

Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE

The ExtendedProtectionFlags parameter specifies custom settings for Extended Protection for Authentication on the virtual directory. Valid values are:

• None: This is the default setting.
• AllowDotlessSPN: Required if you want to use Service Principal Name (SPN) values that don't contain FQDNs (for example, HTTP/ContosoMail instead of HTTP/mail.contoso.com). You specify SPNs with the ExtendedProtectionSPNList parameter. This setting makes Extended Protection for Authentication less secure because dotless certificates aren't unique, so it isn't possible to ensure that the client-to-proxy connection was established over a secure channel.
• NoServiceNameCheck: The SPN list isn't checked to validate a channel binding token. This setting makes Extended Protection for Authentication less secure. We generally don't recommend this setting.
• Proxy: A proxy server is responsible for terminating the SSL channel. To use this setting, you need to register an SPN by using the ExtendedProtectionSPNList parameter.
• ProxyCoHosting: HTTP and HTTPS traffic might be accessing the virtual directory, and a proxy server is located between at least some of the clients and the Client Access services on the Exchange server.

To enter multiple values and overwrite any existing entries, use the following syntax: Value1,Value2,...ValueN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

Parameter properties

Parameter sets

-ExtendedProtectionSPNList

Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE

The ExtendedProtectionSPNList parameter specifies a list of valid Service Principal Names (SPNs) if you're using Extended Protection for Authentication on the virtual directory. Valid values are:

• $null (blank): This value is the default.
• Single SPN or comma delimited list of valid SPNs: The SPN value format is Protocol\FQDN. For example, HTTP/mail.contoso.com. To add an SPN that's not an FQDN (for example, HTTP/ContosoMail), you also need to use the AllowDotlessSPN value for the ExtendedProtectionFlags parameter.

To enter multiple values and overwrite any existing entries, use the following syntax: Value1,Value2,...ValueN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

To add or remove one or more values without affecting any existing entries, use the following syntax: @{Add="Value1","Value2"...; Remove="Value3","Value4"...}.

Parameter properties

Parameter sets

-ExtendedProtectionTokenChecking

Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE

The ExtendedProtectionTokenChecking parameter defines how you want to use Extended Protection for Authentication on the virtual directory. Extended Protection for Authentication isn't enabled by default. Valid values are:

• None: Extended Protection for Authentication isn't be used on the virtual directory. This value is the default.
• Allow: Extended Protection for Authentication is used for connections between clients and the virtual directory if both the client and server support it. Connections that don't support Extended Protection for Authentication work, but might not be as secure as connections that use Extended Protection for Authentication.
• Require: Extended Protection for Authentication is used for all connections between clients and the virtual directory. If either the client or server doesn't support it, the connection will fail. If you use this value, you also need to set an SPN value for the ExtendedProtectionSPNList parameter.

Note: If you use the value Allow or Require, and you have a proxy server between the client and the Client Access services on the Mailbox server that's configured to terminate the client-to-proxy SSL channel, you also need to configure one or more Service Principal Names (SPNs) by using the ExtendedProtectionSPNList parameter.
